Reason:
People can only secrete a small amount of heat when sweating. The accurate statement should be "1 g sweat releases about 580 calories, so the body temperature drops". People only lose weight temporarily when they lose water, and normal weight loss refers to fat reduction. Therefore, it is only the water in the body that often sweats, not the fat.
Precautions:
Many people in life will think it is better to sweat less. In hot summer, some people stay in air-conditioned rooms all day, so that the function of sweat glands remains unchanged and their adaptability will be greatly reduced. The function of sweat is to regulate body temperature and keep the brain functioning normally. Normal people sweat a lot in summer. If they don't sweat at all, heat will accumulate in the body, which will lead to heatstroke and even life-threatening. Of course, sweating too much is bad for your health. When the human body sweats a lot, it is often easy to dehydrate and the blood volume decreases, so the plasma will be concentrated, which will increase the burden on the heart. So when sweating, try to evaporate the sweat, otherwise the liquid in the body will be wasted. Therefore, you should always put on some breathable and loose clothes and pants to stretch your body.
